Tectonic migration is a common geological process during basin formation and development. However,little is known about the tectonic migration in the eastern Junggar Basin. This paper focuses on the eastern part of the Junggar Basin to discuss Mesozoic tectonic migration and its mechanism based on our interpretation of seismic profiles and previous structural results in the eastern part of the Junggar Basin. The eastern Junggar Basin was under intraplate setting in Mesozoic-Cenozoic. Under the southward indentation of the Siberian Plate,the tectonic migration was characterized by progressively southward propagating of faulting,sedimentation,depression,termination of faulting in the basin. Finally,this paper discusses the mechanism and processes of Mesozoic tectonic migration from interplate to intraplate. The migration mechanism of the tectonism-sedimentation-basin formation is related to the Mesozoic extrusion tectonics of the basement of the Junggar Basin and the southward indentation of the Mesozoic Siberian Block.
